While playing minecraft after not having rebooted in a number of days, it complains that the kernel rejected CS, see dmesg for more info.  dmesg shows:

[389509.644744] [drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation -12!
[389509.645383] [drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation -12!

And sometimes, a whole bunch more that I will include at the end of this message.  At first I thought I had a memory fragmentation issue so I forced a compaction but the errors persist.  At the time, free and /proc/buddyinfo show:

psusi at faldara:~/Videos$ cat /proc/buddyinfo

Swap:         2047        499       1548

So it looks to me like I have plenty of free memory, and even in some of the higher order chunk sizes ( this was not the case prior to forced compaction ), so why is radeon complaining -ENOMEM?
